In October 2005, JetBlue's quarterly profit had plunged from US$8.1 million to $2.7 million largely due to rising fuel costs. Operational issues, fuel prices, and low fares, JetBlue's hallmark, were bringing its financial performance down. In addition, with higher costs related to the airline's numerous amenities, JetBlue was becoming less competitive.[citation needed]
On October 31, 2017, the final 757 was retired from service, leaving Allegiant with only their A320 Family and MD-80 series fleets. In November 2018, the last MD-88s operated by Allegiant were retired, with Allegiant now operating an all-Airbus fleet.[85] The move to the newer all-Airbus fleet has allowed Allegiant to benefit from lower fuel and maintenance costs, as well as operate in some airports which could not be served by the MD-80s.[58]
In 1997, Maverick Airways was operating code share service for Frontier with de Havilland Canada DHC-7 Dash 7 STOL capable turboprops between Denver (DEN) and two destinations in Colorado: Grand Junction (GJT) and Steamboat Springs (SBS).[66] However, the service was short lived as Maverick encountered financial challenges and then ceased all flights.
I just had horrendous experience and customer service! I booked a round trip flight for my son from Stockholm to Zurich via Amsterdam. It was 185 USD. Travelocity emailed us on the day of the flight that the flight from Amsterdam to Zurich and all return flights were cancelled. My son ended up booking a new flight from Stockholm to Zurich that costed him about 500 USD. I reached out Travelocity customer service via Facebook. The rep admitted that email was an error but ensured me that return flight was still good. However, my son was charged 285 USD penalty on the return flight for missing the first leg. In the end, he ended up paying 800 USD out of his pocket. Short flight cost us a total of 1000 USD! The reps via Facebook said they were sorry but they would not do anything to compensate/reimburse me or be accountable for their mistakes. I will NEVER use Travelocity again for sure!!
Allegiant Air has been closely monitored by the FAA due to many emergency landings and aborted takeoffs.[56] ABC interviewed a former Allegiant mechanic, who said "Dedicated steps were not being performed with maintenance manuals or even with general practices, before an aircraft is released."[57] Many of these incidents had involved Allegiant's aging MD-80 aircraft, which as of November 2018 have been replaced by newer Airbus A320 family aircraft.[58][50] 46 of the 86 aircraft have made emergency landings, all of which were on MD-80s.[59] The average age of Allegiant's MD-80 fleet was 29 years compared to less than 13 years for its Airbus fleet.[58]

On April 10, 2008, Frontier filed for Chapter 11 bankruptcy in reaction to the intent of its credit card processor, First Data, to withhold significant proceeds from ticket sales.[23][better source needed] First Data decided that it would withhold 100% of the carrier's proceeds from ticket sales beginning May 1.[24] According to Frontier's press release, "This change in practice would have represented a material change to our cash forecasts and business plan. Unchecked, it would have put severe restraints on Frontier's liquidity..." Its operation continued uninterrupted, though, as Chapter 11 bankruptcy protected the corporation's assets and allowed restructuring to ensure long-term viability.[citation needed] After months of losses, Frontier Airlines reported that they made their first profit during the month of November 2008, reporting US$2.9 million in net income for the month.[25]

On August 4, 2008, the Associated Press reported that jetBlue would replace their recycled pillows and blankets with an "eco-friendly" pillow and blanket package that passengers would have to purchase for use. Each package will cost $7 and will include a $5 coupon from retailer Bed, Bath and Beyond. This decision is the latest in a series of moves designed to increase revenue. jetBlue told the Associated Press that it expects to collect $40 million from passengers selecting seats with extra legroom and $20 million from passengers paying $15 to check a second bag. As of September 8, 2008 JetBlue charges passengers $10–30 for an extended-leg-room seat depending on the length of the flight.[37]
I had to make some last minute travel changes and needed to SUBTRACT 2 days from my 9 day car rental reservation. The customer service agent refused to get me to her supervisor after I asked her multiple times because she was trying to charge me more money to take two days off my rental!!! Finally she told me she found something for $205 (my original rental was $268). I said, now that makes more sense. It's the same car? She said yes, I said lets make the change. Then AFTER she completed the transaction she told me that she hadn't added any of the taxes and fees so my new total is $277! Ten dollars more for two days less!! I told her that she mislead me and that she should be ashamed of herself and the company should be ashamed of itself. Obviously it doesn't care about the slew of ONE STAR reviews it has because it's not making any changes to help their customers!

Although it does not fly to Canada, Allegiant advertises extensively there and flies from about a dozen small airports near the Canada–US border. Many of its customers at airports such as Bellingham, Washington (BLI), Niagara Falls, New York (IAG), Ogdensburg, New York (OGS), Grand Forks, North Dakota (GFK) and Plattsburgh, New York (PBG) are Canadians, who can save money by flying from U.S. airports.[35]

jetBlue also utilizes various forms of advertising media. They use print, online, and television ads as well as advertisements on popular social media sites including Hulu and YouTube. jetBlue emphasizes a secondary slogan, "If you wouldn't take it on the ground, don't take it in the air" poking fun at competitors with hidden fees, little, or no amenities and what jetBlue considers an unacceptable level of customer service.[97]

The TWA Hotel is the TWA Flight Center structure currently being rebuilt as 505-room hotel, preserving the Eero Saarinen headhouse while replacing the structures on either side of the headhouse. Situated in front of JetBlue's JFK terminal, JetBlue has stated that it estimates the ownership of the hotel would be between 5–10% of the final total investment.[138] The hotel will be an effective replacement for the Ramada Plaza JFK Hotel on the north end of the airport grounds in Building 144, which closed in 2009.
In October 2013, Republic Airways Holdings entered into an agreement with private equity firm Indigo Partners to sell Frontier Airlines for approximately $145 million. According to Indigo, the transaction would further Frontier's evolution into an ultra-low-cost carrier.[38] In December 2013, Indigo Partners LLC, through an affiliate, completed the purchase of Frontier Airlines from Republic Airways Holdings. The airline's headquarters will remain in Denver.[46] Republic Airways Holdings subsidiary Republic Airlines no longer flies Embraer 190 aircraft on behalf of Frontier, as of January 1, 2014.
In 2011, JetBlue made interline agreements with Virgin Atlantic and Jet Airways, both of which have since been terminated.[112][113] Since 2012, JetBlue has had an interlining agreement with Air China. It also established an interline agreement with Porter Airlines connecting from Billy Bishop Toronto City Airport to US destinations through Boston and Newark.[114]
In March 2011, Allegiant took over charter service to Wendover Airport for Peppermill Casinos, Inc. to shuttle customers to Peppermill's three casinos in West Wendover, Nevada; the Montego Bay Resort, the Rainbow Wendover and the Peppermill Wendover.[45] Allegiant based one 150-seat, MD-80 series jet aircraft in Wendover and more than 20 employees, including maintenance, flight crews and stations personnel.[46]
In summer 2015, a rash of midair breakdowns drew federal scrutiny. "Before the night was finished on June 25, 2015, five Allegiant flights had been interrupted in four hours, all because different planes had failed in midair," reported the Tampa Bay Times.[28] Since October 2015, the Federal Aviation Administration has kept Allegiant under close supervision.[29][30][31] In July 2015, Allegiant Air announced bases would be established at the Asheville Regional Airport and Cincinnati/Northern Kentucky International Airport, becoming the first base at a non-vacation destination.[citation needed]
In August 2017, Allegiant announced a new base would be established at the Indianapolis International Airport. The base began operations in early 2018. In February 2018, Allegiant also announced a new base would be established at the Destin–Fort Walton Beach Airport.
